The PointCloudFilter let's you build expressions from attributes.

ex. @Component(color_red)==@Value(_Red) && @Component(color_green) == @Value(_Green) &&@Component(color_blue)==@Value(_Blue)

It let's you supply a userParameter with an expression

ex @Component(color_red)== 178

It let's you supply an attribute containing a numeric value (ex 178)


But it does not allow you to supply an attribute containing an expression

 |ERROR |Expression Evaluator: Attribute '_ptFilter' has non-numeric value'@Component(color_red)== 178 && @Component(color_green) == 178 && @Component(color_blue)==0'


This makes it very difficult to build dynamic filters where the number of clauses is variable.
